6 Claims.

This invention relstes to electric connecters or the like and more porticulerly to connectors provided with e plurality oi fuses which may be successively used to one or the circuit lines.

It is usual to piece fuses in the line of an electric circuit only where such e. ruse would control e. number of outlets. For this purpose the most couunon type of fuse is messing tyne which re quired changing when blown out". it is else well known to use or fuse plug to control such e. (sir cult in which 9. plurality of fuses ere successively brought into the circuit. It is obviously e dissed vuntoge to have one fuse control plurality of outlets since oil the outlets are rendered inopere= tlve when the trouble, which lies in one of them, blows the fuse.

lit is therefore on important object oi. the invention to provide on electric connector in which plurality oi fuses may be successively brought into the circuit and which is adopted for use in on individual circuit of for inst-once, a floor lamp, radio, toaster outlet, etc.

Another object oi the invention is to provide electric connector of this character which is of simple end durcble construction and in which, by c simple partial turn of 2. con, one of severel fuses in the form of e. cartridge may be brought into the circuit.

Further objects and cdvontcges of the inven= tion will egope'sr from the following disclosure thereof together with the attached drew= lug which illustrates s. preferred form, end in which:

i, is e. longitudinal sectional view of u pre= fora-ed embodiment of the invention.

Fig. 2, is or bottom plan view oi the rotating member.

3. is e. glen view oi the stationary portion.

The connector body of dielectric material may be of substantially cylindrical form end be pro vided with o. control opening e. The body is preferobly also arranged with a. plurality of circular uesssges 7 arranged circumfercnticlly and equally spoced adjacent the outer wall of the body. The goessoges '7 ere adopted to receive fuses 8 in the form. of cartridges oi. any well known form. These curtrldges as here shown ore provided with metal" licceps such as 29-9.

A bese portion 10 of substantially round contour, may be provided with o peripheral flange '11 for engcgement with one end of the body 5 and o cup portion 12 of similar contour may have a flange 13 for engagement with the other end of the body.

The base 10 is arranged with a pair of contact members in the form of projecting prongs or con= tactors 14 and 15. The prong 14 is embedded in the dielectric material of the base and has elec-- trical connection such as at 16 with a. plate 17 nested in the inner portion of the base.-

There is preferably struck from the piste 17, e. plurality of contact fingers 18 equal in number to the number of fuse cartridges and these are struck. up to such a. degree as to have engagement within the respective passages l of the body.

The pr mg is fixed to the base plots 10 by means such as the rivet 19 rind has on inreeching portion 20 terminating in a spherical end 21. spherical end is positioned over the exact center oi the base piste l0.

The con 12 which may be provided with e. knurled or roughened periphery carries a pair oi? spring contact members or plug connectors 22 one. 23, the member 22 being secured to the cup by moons such as the rivet 2% provided with 2. contact heed 25 and the member 23 being secured to the can by the rivet 26, the head of which is countersunk below the inner face of the cup.

The contact member 23 is provided with or branch. portion 27 terminating in o. soclret member 22 adopted to engage the spherical erd 21.

The can 12 is further provided with openings 29 receptive oi the prongs of e. standard electric ettechment plug and these openings are nrefcrably in registereble alignment with the spring contact members 22 and 23.

As can be seen from the foregoing on electric connector is provided in which any one or the fuse cartridges 8 may be positioned to bridge the terminals 14 and 22. Should the cartridge so positioned blowwut, a simple partial turn of the cop will bring the adjacent cartridge into the bridging position.

When all the fuses are blown-out, the connector may be separated by disengaging the spherical end 21 from the socket 28 and the "blovro fuses replaced. The end 21 and socket 23 they then be re-engaged by an end-wire push on the base 1c and can 7.2.

Inadvertent rotation between the body 5 end base to is prevented by the keying action of the portions 18 in the passages 7 and these por tions are slightly resilient to insure good electric contact between the head 25 and cartridge end 9 and cartridge end 9' and contest fingers l8.

fr rom the foregoing it will be seen that as simple device for the purpose has been dlsclosed in the preferred form of its embodiment but it is not desired to restrict the details to the exact construction shown, it being obvious that changes, not involving the exercise of invention, may be made without departing from the scope of the appended claims.

Having thus described my invention what I claim as new and desire to secure by Letters Patent, is:

1. An electric connecter comprising a body housing, forming a shell, having a wall of substantial thickness, a plurality of fuse cartridges located within said wall, a base closure covering one end of said housing, means to interconnect at said closure one terminal each of all of the fuse cartridges, a rotatable, removable closure at the other end of said housing, means on said removable closure to contact, one at a time, the second terminal of the fuse cartridge, plug connecters on the removable closure and contactors protruding from the base closure, one of said contactors and plug connecters to serve as terminals for one of said fuses and the other of said contactors toc'onnect with the remaining plug connecter.

2. An electric connecter comprising a body housing forming a shell, a plurality of fuse cartridges interchangeably located within the wall of said housing, a base closure covering one end of said housing, means to interconnect at said closure one terminal each of all of the fuse cartridges, a rotatable, removable closure at the other end of said housing, means on said removable closure to contact, one at a time, the second terminal of the fuse cartridges, plug connecters on the removable closure and contactors protruding from the base closure, one of said contactors and plug connecters to serve as terminals for one .of said fuses and the other of said contactors toconnect with the remaining plug connecter and means to flexibly connect the remaining connecter with said other connecter.
